OPEN-1 Concept

"OPEN-1: one synth, every firmware.

OPEN-1 is an idea for an open, entry-level synth: a 37-key instrument that becomes a new machine every time you pick a firmware from the SD card. In this concept video it runs a simulated HYP-1, in time with a real HYP-1 live take.

IDEAS PHASE: OPEN-1 is not a product yet. Nothing is for sale, the renders are concept art, and every spec and price below is a target, not a promise. I'm sharing it early to find out what you'd want from it.

TARGET SPECS
480 MHz Cortex-M7 (STM32H750), open toolchain (the FM-1 runs at 240 MHz)
32 MB of working memory for long delays, loops and samples (the FM-1 has about 432 KB)
16 MB of firmware flash plus a microSD library: keep several firmwares installed, swap from the menu
24-bit stereo audio in AND out, so it can be an effects box too
MIDI in and out (3.5 mm TRS), USB-C device and USB-C host
37 RGB-lit silicone keys, 8 velocity pads, 8 endless encoders, a thumbstick and 2 spring levers
4" 480×320 IPS screen, built-in speaker, headphone out, 3000 mAh battery
Wired only, no Bluetooth: lower latency, simpler to build
Target price: under $200

OPEN BY DESIGN
An open SDK and a browser emulator, so developers can build firmware before the hardware ships
A firmware jam before launch, with a community-voted firmware pack preloaded on every unit
Launch firmware ported from the FM-1 family: HYP-1, LOF-1, ECO-1 and GRAV-1
